"Tissue created with microblood vessel network and integrated the tissue into mice - a major advance for bioprinting organs"
New research, led by nanoengineering professor Shaochen Chen, addresses one of the biggest challenges in tissue engineering: creating lifelike tissues and organs with functioning vasculature ? networks of blood vessels that can transport blood, nutrients, waste and other biological materials ? and do so safely when implanted inside the body.
"Novel Flexible Glove-Based Biosensor for Detecting Organophosphates"
Organophosphates are toxic chemicals used as pesticides in agricultural practice and as nerve agents in biological warfare. Exposure to organophosphates can cause severe illness or death if appropriate safety measures are not taken. Rapid and accurate point-of-use detection of organophosphate pesticides or nerve agents would improve security in both food safety and defense scenarios. A recent study published in the journal ACS Sensors describes a novel flexible, wearable, disposable glove-based biosensor that detects organophosphate compounds in real-time.

"Wearable Sensor Detects On-Site Chemical Threats"
Certain chemical compounds known as organophosphates are used as the foundation for many herbicides, insecticides, and nerve agents. Even though they are widely employed, these biochemicals carry dangerous side effects when exposed directly to humans. Researchers have recently developed a fast and efficient way to detect the existence of these deadly compounds. Referred to as a ?lab-on-a-glove,? a disposable glove decked out with a flexible sensor may be able to reveal and warn the wearer of nearby harmful substances.

"Nanowire retinal implant could restore sight with better resolution"
Advances in bionic eyes over the past few decades have given blind and visually impaired people new hope of restoring some of their vision. Now engineers have tested a new nano-scale system that could be implanted onto a patient's retina to respond to light by directly stimulating the neurons that send visual signals to the brain. Unlike other systems, the new device wouldn't require any external sensors, and can provide a much higher resolution.

"Robotic head of sci-fi author Philip K Dick being used to teach doctors how to recognise pain in patients"
Humanoid, facially expressive robots have been designed by researchers to help medical professionals improve their diagnosing skills. While robotic patient simulators (RPS's) are already used to train doctors, their faces don't move and don't express emotions. So researchers created a robot with rubber skin that can move its facial features to express real human emotions. The research team, led by Dr Laurel Riek, an associate professor of computer science and engineering at UC San Diego, designed the robot to be able to express pain, disgust and anger.
"New Wirelessly Powered Scalable Retinal Prosthesis"
A collaboration between researchers at University of California San Diego and Nanovision Biosciences, a university spinoff, has developed a method for constructing wirelessly powered retinal prostheses that interface directly with retinal cells. The implant is structured from photosensitive silicon nanowires and, because they produce a textured surface, retinal cells are able to grow on them. Powering the array is a novel wireless system, that sits on the head near the eye, and provides current to all the nanowires simultaneously.

"Novel nano-implant may help restore sight"
Scientists have developed a high-resolution retinal prosthesis using nanowires and wireless electronics that may aid neurons in the retina to respond to light. The technology could help tens of millions of people worldwide suffering from neurodegenerative diseases that affect eyesight, including macular degeneration, retinitis pigmentosa and loss of vision due to diabetes. In the study, detailed in the Journal of Neural Engineering, the researchers demonstrated this response to light in a rat retina interfacing with a prototype of the device in vitro.

"Blood test could detect and locate cancer at early stage"
Researchers have developed a new blood test that can not only detect cancer at an early stage, but can also indicate where the tumour is located in the body. So-called 'liquid biopsies' detect fragments of tumour DNA called cell-free DNA (cfDNA), but until now they have only been able to detect the presence or absence of a tumour. Professor Kun Zhang of the University of California, San Diego, and colleagues found that normal cells that compete with cancer cells for nutrients and space also release their DNA in the bloodstream. This DNA leaves organ-specific signatures ? known as CpG methyla
"Science Inches Closer to a Universal Blood Test for Cancer"
A universal blood test for any type of cancer is an oncologist?s dream come true, and a new study suggests this concept may soon become a reality. Research from the University of California, San Diego, has found a new way to detect cancer in the blood that could both alert doctors to the presence of cancer, and tell them where in the body the tumor is located. The new study, published online in the journal Nature Genetics, describes the discovery of a new clue found in the blood. Although the discovery is preliminary, the team hopes to soon advance to the clinical stage where it can be tested.

"Report: New blood test could detect location of cancer in body!"
Researchers are developing a blood test that can tell not only whether someone has cancer, but in what organ the tumors are lurking. The test could mean more prompt, potentially life-saving treatment for patients. Researchers describe their blood test as a kind of dual authentication process. It is able to detect the presence of dying tumor cells in blood as well as tissue signatures, to signal to clinicians which organ is affected by the cancer.

"Robot that shows pain could teach doctors to recognise it better"
Can you recognise when someone is unwell just by studying their face? Understanding expressions can help doctors improve their diagnoses, but it's a difficult skill to practise. So a group of engineers have made a tool for training clinicians: a robot that can express pain. Many doctors already use robotic patient simulators in their training to practise procedures and test their diagnostic abilities. "These robots can bleed, breathe and react to medication," says Laurel Riek at the University of California, San Diego. "They are incredible, but there is a major design flaw - their face."
